Hi

Find a general form equation for the line through points (-2,-3) and (8,-1)

Using the point-slope formula, 

(-2,-3) 

 (8,-1)  m = -2/-10 = .2

Using the standard slope-intercept form for an equation of a line y = mx + b  where m is the slope and b the y-intercept.  

  y = .2x + b

 -3 = -.4 + b

   -2.6 = b

 y = .2x -2.6
